Magnesium Oxide is a food-grade versatile mineral compound used as an anti-caking agent, acidity regulator, magnesium supplement and refractory material across food, pharmaceutical and industrial applications.We supply bulk Magnesium Oxide sourced from leading China manufacturers, available in powder form for international food processing operations. Our Magnesium Oxide is widely used in food powders, magnesium dietary supplement, food processing, pharmaceutical antacid and refractory lining material.
Magnesium Oxide (MgO) is produced by calcining magnesite or precipitated magnesium carbonate. Food-grade MgO (light or heavy grade) contains approximately 60% elemental magnesium and serves as an anti-caking agent, acidity regulator, desiccant and magnesium fortification source.
It has high neutralising capacity and is used in pharmaceutical antacids. Industrial grades serve as refractory linings, electrical insulation and environmental remediation.
